    廣泛應(yīng)用于鋼鐵、冶金、鋁行業(yè)、石油化工、航天、船舶制造、煤炭、水泥、電力、汽車、工程機械、食品、藥業(yè)、林業(yè)、紡織、皮革、造紙等行業(yè)領(lǐng)域

    齒輪泵的概念是很簡單的,即它的zui基本形式就是兩個尺寸相同的齒輪在一個緊密配合的殼體內(nèi)相互
    嚙合旋轉(zhuǎn),這個殼體的內(nèi)部類似“8”字形,兩個齒輪裝在里面,齒輪的外徑及兩側(cè)與殼體緊密配合。來自于擠出機的物料在吸入口進入兩個齒輪中間,并充滿這一空間,隨著齒的旋轉(zhuǎn)沿殼體運動,zui后在兩齒嚙合時排出。
    在術(shù)語上講,齒輪泵也叫正排量裝置,即像一個缸筒內(nèi)的活塞,當(dāng)一個齒進入另一個齒的流體空間時,液體就被機械性地擠排出來。因為液體是不可壓縮的,所以液體和齒就不能在同一時間占據(jù)同一空間,這樣,液體就被排除了。由于齒的不斷嚙合,這一現(xiàn)象就連續(xù)在發(fā)生,因而也就在泵的出口提供了一個連續(xù)排除量,泵每轉(zhuǎn)一轉(zhuǎn),排出的量是一樣的。隨著驅(qū)動軸的不間斷地旋轉(zhuǎn),泵也就不間斷地排出流體。泵的流量直接與泵的轉(zhuǎn)速有關(guān)。
    實際上,在泵內(nèi)有很少量的流體損失,這使泵的運行效率不能達到*,因為這些流體被用來潤滑軸承及齒輪兩側(cè),而泵體也絕不可能無間隙配合,故不能使流體*地從出口排出,所以少量的流體損失是必然的。然而泵還是可以良好地運行,對大多數(shù)擠出物料來說,仍可以達到93%~98%的效率。


    對于粘度或密度在工藝中有變化的流體,這種泵不會受到太多影響。如果有一個阻尼器,比如在排出口側(cè)放一個濾網(wǎng)或一個限制器,泵則會推動流體通過它們。如果這個阻尼器在工作中變化,亦即如果濾網(wǎng)變臟、堵塞了,或限制器的背壓升高了,則泵仍將保持恒定的流量,直至達到裝置中zui弱的部件的機械極限(通常裝有一個扭矩限制器)。
    對于一臺泵的轉(zhuǎn)速,實際上是有限制的,這主要取決于工藝流體,如果傳送的是油類,泵則能以很高的速度轉(zhuǎn)動,但當(dāng)流體是一種高粘度的聚合物熔體時,這種限制就會大幅度降低。
    推動高粘流體進入吸入口一側(cè)的兩齒空間是非常重要的,如果這一空間沒有填充滿,則泵就不能排出準確的流量,所以PV值(壓力×流速)也是另外一個限制因素,而且是一個工藝變量。由于這些限制,齒輪泵制造商將提供一系列產(chǎn)品,即不同的規(guī)格及排量(每轉(zhuǎn)一周所排出的量)。這些泵將與具體的應(yīng)用工藝相配合,以使系統(tǒng)能力及達到*。
    PEP-II泵的齒輪與軸共為一體,采用通體淬硬工藝,可獲得更長的工作壽命。“D”型軸承結(jié)合了強制潤滑機理,使聚合物經(jīng)軸承表面,并返回到泵的進口側(cè),以確保旋轉(zhuǎn)軸的有效潤滑。這一特性減少了聚合物滯留并降解的可能性。精密加工的泵體可使“D”型軸承與齒輪軸精確配合,確保齒輪軸不偏心,以防齒輪磨損。Parkool密封結(jié)構(gòu)與聚四氟唇型密封共同構(gòu)成水冷密封。這種密封實際上并不接觸軸的表面,它的密封原理是將聚合物冷卻到半熔融狀態(tài)而形成自密封。也可以采用Rheoseal密封,它在軸封內(nèi)表上加工有反向螺旋槽,可使聚合物被反壓回到進口。為便于安裝,制造商設(shè)計了一個環(huán)形螺栓安裝面,以使與其它設(shè)備的法蘭安裝相配合,這使得筒形法蘭的制造更容易。


    PEP-II齒輪泵帶有與泵的規(guī)格相匹配的加熱元件,可供用戶選配,這可保證快速加溫和熱量控制。與泵體內(nèi)加熱方式不同,這些元件的損壞只限于一個板子上,與整個泵無關(guān)。

    齒輪泵由一個獨立的電機驅(qū)動,可有效地阻斷上游的壓力脈動及流量波動。在齒輪泵出口處的壓力脈動可以控制在1%以內(nèi)。在擠出生產(chǎn)線上采用一臺齒輪泵,可以提高流量輸出速度,減少物料在擠出機內(nèi)的剪切及駐留時間。
    外嚙合齒輪泵是應(yīng)用zui廣泛的一種齒輪泵,一般齒輪泵通常指的就是外嚙合齒輪泵。它的結(jié)構(gòu)如圖5-14所示,主要有主動齒輪、從動齒輪、泵體、泵蓋和安全閥等組成。泵體、泵蓋和齒輪構(gòu)成的密封空間就是齒輪泵的工作室。兩個齒輪的輪軸分別裝在兩泵蓋上的軸承孔內(nèi),主動齒輪軸伸出泵體,由電動機帶動旋轉(zhuǎn)。外嚙合齒輪泵結(jié)構(gòu)簡單、重量輕、造價低、工作可靠、應(yīng)用范圍廣。
    齒輪泵工作時,主動輪隨電動機一起旋轉(zhuǎn)并帶動從動輪跟著旋轉(zhuǎn)。當(dāng)吸入室一側(cè)的嚙合齒逐漸分開時,吸入室容積增大,壓力降低,便將吸人管中的液體吸入泵內(nèi);吸入液體分兩路在齒槽內(nèi)被齒輪推送到排出室。液體進入排出室后,由于兩個齒輪的輪齒不斷嚙合,使液體受擠壓而從排出室進入排出管中。主動齒輪和從動齒輪不停地旋轉(zhuǎn),泵就能連續(xù)不斷地吸入和排出液體。
    泵體上裝有安全閥,當(dāng)排出壓力超過規(guī)定壓力時,輸送液體可以自動頂開安全閥,使高壓液體返回吸入管。
    內(nèi)嚙合齒輪泵,它由一對相互嚙合的內(nèi)齒輪及它們中間的月牙形件、泵殼等構(gòu)成。月牙形件的作用是將吸入室和排出室隔開。當(dāng)主動齒輪旋轉(zhuǎn)時,在齒輪脫開嚙合的地方形成局部真空,液體被吸入泵內(nèi)充滿吸入室各齒間,然后沿月牙形件的內(nèi)外兩側(cè)分兩路進入排出室。在輪齒進入嚙合的地方,存在于齒間的液體被擠壓而送進排出管。
    齒輪泵除具有自吸能力、流量與排出壓力無關(guān)等特點外,泵殼上無吸入閥和排出閥,具有結(jié)構(gòu)簡單,流量均勻、工作可靠等特性,但效率低、噪音和振動大、易磨損,用來輸送無腐蝕性、無固體顆粒并且具有潤滑能力的各種油類,溫度一般不超過70 ℃,例如潤滑油、食用植物油等。一般流量范圍為0.045~30ms/h,壓力范圍為0.7—20MPa,工作轉(zhuǎn)速為1200—4000r/min。
    結(jié)構(gòu)特點


    (1)結(jié)構(gòu)簡單,便宜;


    (2)工作要求低,應(yīng)用廣泛;
    (3)端蓋和齒輪的各個齒間槽組成了許多固定的密封工作腔,只能用作定量泵。
    齒輪采用具有九十年代*水平的新技術(shù)--雙圓弧正弦曲線齒型圓弧。它與漸開線齒輪相比,zui突出的優(yōu)點是齒輪嚙合過程中齒廓面沒有相對滑動,所以齒面無磨損、運轉(zhuǎn)平衡、無困液現(xiàn)象,噪聲低、壽命長、效率高。該泵擺脫傳統(tǒng)設(shè)計的束縛,使得齒輪泵在設(shè)計、生產(chǎn)和使用上進入了一個新的領(lǐng)域。


    泵設(shè)有差壓式安全閥作為超載保護,安全閥全回流壓力為泵額定排出壓力1.5倍。也可在允許排出壓力范圍內(nèi)根據(jù)實際需要另行調(diào)整。但是此安全閥不能作減壓閥*工作,需要時可在管路上另行安裝。
    該泵軸端密封設(shè)計為兩種形式,一種是機械密封,另一種是填料密封,可根據(jù)具體使用情況和用戶要求確定。
    泵的分類


    就核心組成部件齒輪而言,主要由公法線齒輪泵和圓弧齒輪泵。公法線齒輪泵輸送含雜質(zhì)的介質(zhì)比圓弧齒輪泵要耐用,而圓弧齒輪泵結(jié)構(gòu)特殊,輸送干凈的介質(zhì)噪音低,壽命長,各有各的優(yōu)點。
